The human brain is capable of processing thousands of sensory signals and provide biological orders each second. How to process? Scientists must simulate the workings of the human brain with 100 billion cells her nerves to find out.
Whether robots could be equipped with feelings and consciousness? To realize this vision, scientists need a control center based in the human brain. This is a superlative project and aims to understand the brain and simulate on the computer.
Alois Knoll of the Technical University of Munich is one of many scientists in Europe are attempting to unravel the workings of the brain. “The basic Idea of the Human Brain project is creating computer simulations of as much brain function of mammals. So first step, one must understand how all this works. How do neurons or components of brain functioning. How they cooperate and how to replicate the workings of them through a computer, which basically manipulate numbers. "
When compared to the human brain, the brain of rats with 70 million neurons are very small, but its structure is similar. So the first step is the simulation of a rat's brain is not too complicated. And associated with the question, how the brain conveying information to the virtual body. The brain processes the impression of censorship and produce a biological command, for example, trigger a reaction to emotions. How about the way this process?
To reproduce the human brain which had 100 billion neurons, 93 should be more than one giant supercomputer. With 150,000 processor, something called SuperMUC in Munich is one of the largest computers in the world. And that alone is not enough for the simulation of the human brain.
Prof. Alois Knoll: "If the roundabout capacity a neuron in the form of computer capacity, may arguably, a computer such as SuperMUC only got a quarter of a percent of the capacity of the human brain."
When talking about pure mathematics, humans can even lose with a small calculator that can be placed in the Pocket. Instead, the man was able to capture the meaning of the situation around us in a few seconds, as well as distinguishing between important and unimportant information. While the computer is in a short time to be overwhelmed if entered data is not filtered. Moreover, the high-capable computers need electricity as much as they needed a small town. While the brain needs only as much energy as needed light bulbs.
The new computer generation will get the human brain and the way of functioning as a certain pattern, as is the case in what is called the SpiNNaker-Chips. "SpiNNaker combines each of 18 simple ARM processor in a chip with a simple network that allows data exchange-traded between 18 this chip in a way that is not normally done, that are asynchronous", said Knoll.
Asynchronous is communication of process data that is not bound by a fixed time, the speed of the process of transformation of its data is quite relative and not fixed.
In order to test their simulations, scientists have developed a new type of robot that is planned to be able to implement the tasks given by the virtual brain, such as the process of movement. A robot with a mechanical system of the human body and the spinal nerves also elastic, and joints. The goal, so that the robot can move flexibly like humans. But for that, the robot must be controlled with appropriate sensitivity.
Informatics experts Dr. Florian Röhrbein: "The biggest challenge On this anthropometric is a robot requires a new control structure because people don't have motor movers on the joints as in robots used in industry. Here the robot got nerves, joints, and bones. And this is a major challenge for science, to develop a strategy of control. And for that, we can also imitate the brain. We can see from nerve science, how humans control the joints. "
There is still much research to be done, before the virtual brain capable of controlling the body of the machine perfectly. If a robot is expected will be pure can show feelings, then scientists must first understand Systematics of the human brain.
